/Applicaton filed March 22, 1920. Serial No. 367,666.

To @ZZ 'whom t may concern Be it known that l, @Hannes S. lNoons, a citizen of the United States, and a resident of Indianapolis, county of Marien, and State of Indiana, have invented a certain newand useful lVindow-Ventilator; and l do hereby declare that Ythe following is a full, clear, and exact description thereof, reference being had-to the accompanying drawings, in which like numerals refer te like parts.

The object of this invention is to provide practical Ventilating means for windows suitable for hospitals, o''lices, residencesand other' use, arranged so hat 'the defiector, which is made of glass, can be carried by the window sash when the ventilator is not in use and thus be relatively outJ of the way'and not shut out the light and yet the the window sill and in such association with the window sash las to permit the latters elevationy independently of the deflector.

This construction furnishes all the advantages of the ordinary deflector construction in ventilators and yet permits the deflector to be mounted on the window sash and be elevatedl with the window sash in mild weather when it is unnecessary to de'iect the current of air upward. Also the deflectOr will be folded on and carried by the window sash when the room is not being` used or ventilation is not desired.

The full nature of this invention will be understood from the accompanying drawings and the following description and claims. v y

ln the drawings Figure l is an inside elevation of the window equippedV with said Ventilating means in position of opcratimi.` the window sash being open. F 2 is a central vertical section ofthe lower part thereof. Fig. 3 is ,a horizontal section of F ig. l just above the Ventilating mechanism. Fig. d is a similar section with the detlecter mounted on the window sash. Fig. 5 is a section similar to Vthat shown 'in Fig. 2 with the deilector mounted on the window sash and the window sash closed. Y

There is shown herein a window rsash l0 having an upper sash 1l and a lower sash 12, and window sill 13, the usual construction.

A verticalgroove Y2() is of the lower window sash cut in each side extending from said parts being of` `is mounted upon the the bottom of the window sash up as far as desired, herein about halfthe height of the sash, and in each of said grooves a vertical iron rod 21 is secured. To the lower lrail of each window sash a vmetal arm 22 is secured so as to project inward, and its inner end is turned upward hook like.

An air current Cle-Hector is provided con.

sisting of a central glass plate 25, the length of which is less than the width of the window sash, and two end Vextensionplates 26 o f the same height as the plate 25 but relatively` short and placed againstthe inner face of the plate 25. For the purpose of adjusting the length of the deflector, each of these vplates is surrounded by a metal frame 27, preferably, but not necessarily. A shoe 30 covers the lower edges of said "metal plates, as lshown in Fig. `2. lt consists of angle iron plates secured to the glass vframes and adapted torest on the window sill. Thereis a similar short metal holder 31 "secured on the upper edges of said plates at their overlapping portions. and holder 3l are rigidly secured to the cen tral deflector 25, but the extension plates 26 slide longitudinally in said holders so that they may be adjusted, `The holders 31 are flexibly connected with the rods 2l so as to slide up and down thereon. This flexible connection consists of three metal bars 32, 33 and 34e hinged together in succession with oppositely operating hinges.` The bar 34 isl slidable on the rod 21 while the bar 32 is secured to the holder 31.

lWhen the deliector is in use, as in Figs. Il, 2 and 3, the deflector plate is placed in vertical position on the base board and lengthened bythe extension 26 so as to overf lap and engage the inner faces of the window casing, as seen in Figs. land 3. The deflector is held in vertical position by the flexible connection at the. upper edges thereof, as shown in Fig. 2. Then the lower window sash is elevated as shown, or as desired. l Y

lNhen the ventilator is not in use it is folded up and mounted on they window sash, as shown in Figs. i and 5. All that is necessary to effectl this is to slide toward each other the two end plates 26 so as to make the total deflector of less width than the window sash, as seen in Fig. '4h Thenthefdeiiector This shoe 30y arms 22, whereby it is.

carried, and the flexible connection at the upper edge of the deflector permits the upper portion of the deifiector to beplaccd against the window sash, whereby it can be held by the hook or latch l0 which is yieldingly mounted in the window sash so catch over the top of the deflector after is folded up in place on the window sash. When in this position the window sash can be elevated, lowered and used `the saine if there were no ventilator and the ventilator will not interfere or shut 'out the light.

The foregoing drawings and description explains the general nature of this invention, but it is understood that the invention is not limited to the particular detailed. construction set forth herein for illustrating said invention.

It will be obvious that various constructions other than that shown herein may be used in place ofthe rods 21, and the connecting bars 32, 33 and 34, such as a bar having eye cennections at both ends, slidable in a metal groove secured to the sash. rlfherefore, it is not desired to limit this'invention to these details of construction of which there may be several various types all cooperating in the same manner.

The invention claimed is:

1. VThe combination with a window casing having a sill and a window sash in the casing, of anV air deflector extending transversely of the window and flexibly connected Vwith the window sash so that it may be spaced inwardly therefrom and be supported on the window sill and permit the independent opening of the window sash for ventilation, and means yfor supporting it by and against the window sash when not in use 2. The combination of a window casing having vertical side faces and a window sill, and a window sash, of an air deflector extending transversely of the window and flexibly connected with the window sash so that it may be spaced inwardly therefrom and be supported on the window sill and permit the opening of the window sash for ventilation, said delector being longitudinally-,extensible so that when in position for use it may be extended to permit its ends to engage the facing of the window casing at each side and when not in use be shortened so that its length will not exceed the length of the window sash, and means for supporting it when contracted by and against the window sash when not in use.

3. The combination with a window casing having a vertical side face and a window sill, and a window sash, of an air deflector extending transversely of the window and flexibly connected at its upper edge with the window sash so that it may be spaced inwardly therefromV and be supported on the window sill and permit the opening of the windowV sash for ventilation, said dellector consisting of a central plate of less length than the width of the window sash and extension plate of the same height as the central plate and longitudinally slidable adjacent each end of said central plate for increasing or decreasing the length of the deflector, and means for supporting it when contr cted by and against the window sash when not in use.
